Press 2 buttons

brunokc:
yes i have a 10k ohm resistor as puldown on both buttons.

If you have pulldown resistors in place then

if(digitalRead(Buttonup) == LOW)
  {
    DebounceUp++;
  }else 
   {
    DebounceUp = 0;
    ButtonUpPressed = false;
    Toggle = false;
   }

does not make sense to me as the Buttonup pin will be LOW most of the time.

Maybe I have misunderstood what you are doing.
